三(三溴新戊醇基)磷酸酯在阻燃HIPS中的应用

Application of Tris (tribromoneopentyl) phosphate in Flame Retardant HIPS

研究了三(三溴新戊醇基)磷酸酯阻燃剂在阻燃高冲击强度聚苯乙烯中的应用,并与多溴二苯醚和溴化邻苯二甲酰亚胺衍生物进行了对比,结果表明:三(三溴新戊醇基)磷酸酯非常适用于阻燃高冲击强度聚苯乙烯。在UL94V—2级阻燃体系中,溴含量70%和磷含量3%的结合使阻燃剂用量小,而且产品有非常好的流动性,并有着显著的抗紫外线特点。

Compareing with decabromodiphenyl oxide（DBDPO） and ethylene-bis（tetrabromophthalimide） derivates, the results show that tris （tribromoneopentyl） phosphate is more suitable for flame- retardant HIPS. In the flame-retardant system of UL94V-2 grade, it makes the use amount of the flame-retardant reduce to bromine 70% combinated with phosphorus 3%, the product＇s flow ability becomes excellent, and it has outstanding anti-UV features.
